Title: Ink absorbing device of ink jet printer
Inventor: NAKAHARA JUNJI
IPC: B41J2/18
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To enhance ink absorbing efficiency by effectively putting an absorbing material to practical use over a wide range in an ink absorbing device for absorbing and holding waste ink generated by the maintenance operation of an ink jet recording head. SOLUTION: A rectangular parallelpiped absorbing material 5 composed of a porous material such as pulp is housed in an upwardly opened rectangular parallelepiped container and a slit 9 is formed to the surface 5b of the absorbing material 5 along the diagonal line passing one apex 5a. The ink 227 dripped on the slit in the vicinity of the apex 5a is rapidly diffused along the slit 9 by its surface tension and absorbed at the position along the total length of the slit over a wide range at the same time. Therefore, the ink 227 dripped on the absorbing material 5 is rapidly absorbed and, therefore, even if vibration is applied immediately after dripping, the scattering of the ink 227 to the circumference can be certainly prevented.

Title: Recorder
Inventor: SHIKINO KAZUTO
IPC: B41J2/165
Filed: 1985-10-24
Abstract: PURPOSE:To prevent a fold of a film and generate a convection from the pulley side toward outside the film to stabilize a cleaning of holes in the film and an ink filling therein, by a method wherein a pulley is composed of a plurality of vanes disposed at some angles to the center of rotation. CONSTITUTION:Ink intake ports 8c are provided on a disc 8a and vanes 8b are twistedly disposed at some angles to an axis of rotation of a pulley. A film 2 is fed into an ink tank 6 by rotation of a capstan 3 driven by a motor unit 5, thus wound round an approximately half circumference of a roller 8 to rotate the roller 8. At this time, the ink supplied from the ink intake ports 8c is discharged in the peripheral direction of the roller 8 by the vanes 8b. This ink flow passes through holes in the film 2 wound round the roller 8, thus acting so as to push out a dust and ink residue adhered in the holes and then fill the holes with a new ink. Selective heating of a thermal head 1 allows the ink to fly due to bubble pressure to conduct printing on a recording paper disposed opposedly to the thermal head 1 and the film 2.

A polymerizer having the inner wall coated with an agent which prevents the adhesion of a vinyl chloride polymer is used. The temp. after the completion of charging the aq. medium and the monomer is set at 40 deg.C or lower. The water/monomer ratio (the wt. ratio of an aq. medium/a monomer) after the completion of charging is set at 0.40-0.80 and is adjusted to 0.60-1.20 by the addition of the aq. medium after the temp. of the polymn. system is raised and before the conversion of the monomer into a polymer reaches 10%.  Pref., at least one partially saponified polyvinyl alcohol having a degree of saponification of 70-85 mol.% and an average degree of polymn. of 500-3,000 is used as the dispersion stabilizer.

Title: Automatic gain control amplifier circuit
Inventor: ATSUTA HIROSADA
IPC: H03G3/20
Filed: 1989-09-14
Abstract: PURPOSE:To simplify adjustment of the level of a limiter by operating a post- stage voltage controlled attenuator with a difference voltage caused between limiter input and the output at an AGC voltage of a limiter level or over, and operating a pre-stage voltage controlled attenuator with a difference voltage caused between limiter input and the output at an AGC voltage of a limiter level or below. CONSTITUTION:A limiter for a post-stage voltage controlled attenuator 1b is not required, instead a differential amplifier 8a detecting a difference voltage between the input voltage and the output voltage of a limiter 7a to limit the control voltage of a pre-stage voltage controlled attenuator 1a is provided. Then the output voltage of a differential amplifier 8a is applied to a level adjustment circuit 3b, and the resulting output voltage is fed to the post-stage voltage controlled attenuator 1b as a control voltage. Thus, the entire attenuation in an AGC amplifier circuit is distributed from the post-stage voltage controlled attenuator with priority to improve the noise figure(NF) in the best condition. Thus, the required AGC characteristic at a high NF characteristic is obtained by having only to adjust the limiter level of the limiter 7a.

CONSTITUTION:A metallic pad 14 whose thermal expansion coefficient is close to that of a crystal chip such as copal and whose thickness is nearly 0.1mm is fixed to a support electrode 12 and the end of a crystal chip 15 is placed on the metallic pad 14 and fixed. The orientation of the crystal of the crystal chip 15 is cut at a prescribed angle to the crystal axis, the chip 15 is formed as a plate and an exciting electrode is formed on the plate face. Then the exciting electrode is led out externally via the metallic pad 14, the support electrode 12 and the mount electrode 13. Then a cover 16 is covered on the upper face of the base 12 to apply air-tight sealing. Since the degree of the expansion/contraction due to the thermal expansion of the base reaching to the crystal chip is decreased, excellent resonance and aging characteristics are attained.

Title: Heat treatment for weld zone
Inventor: OKI SHIGEAKI
IPC: C21D9/50
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To securely recover the toughness in a weld zone, after flash butt welding, uniformly in a thickness direction as well as in a width direction by means of short-time heat treatment. SOLUTION: The tail end of a preceding steel strip and the head end of a succeeding steel strip are joined and welded. At the time of heat treatment for the resultant weld zone by means of heating using a burner, a distance between the burner and the steel strip and a heating time are previously set, for each plate thickness and material. The distance between the burner and the steel strip is selected according to plate thickness or material or plate thickness and material, without changing the amount of combustion of the burner, and the distance between the burner and the steel strip is regulated by vertically moving the burner or a cramp fixing the steel strip. Then, heat treatment is performed by heating by the use of the burner for the selected heating time.  By this method, uniform heating can be securely applied in a short time to the weld zone in the width and the thickness direction to recover toughness, and the occurrence of breakage in the jointed zone in the continuous treatment line can be prevented.

Abstract: PURPOSE:To stabilize the wavelength of a laser light source, by controlling the optical path of an optical resonator in the manner in which the resonance wavelength of the optical resonator is made to coincide with the wavelength of the laser light source. CONSTITUTION:The emitted light 11 from an optical resonator (ring resonator) 27 is analyzed with an analyzing means constituted of a quarter wave plate 12 and a polarization beam splitter 13. The quantitative relation and its degree of the resonance wavelength of an optical resonator 27 and the wavelength of a laser light source 1 are detected. By using the results, an optical length changing means (piezo actuator) 17 is controlled with a second controller 16, and the resonance wavelength is made to coincide with the wavelength of the laser light source. At the same time, the wavelength of the laser light source is controlled with a first controller 21 so as to coincide with the wavelength of saturable absorption spectrum of an absorption cell 9. Thereby the resonance wavelength is made to coincide with the wavelength of the saturable absorption spectrum, and the light intensity in the optical resonator is made equal to the light intensity capable of sufficiently saturating absorption lines. In the above state, the wavelength of the laser light source is controlled with the first controller 21 so as to coincide with the wavelength of the absorption spectrum. Hence the wavelength of the laser light source is stabilized.
